Amorphous alloy transformers typically feature a compact and lightweight design, with a rational structure and refined craftsmanship. The specific characteristics are as follows:
I. Overall Structural Features
1. Compact Design
Amorphous alloy transformers utilize specialized structural optimizations, such as "three-phase five-limb" or "three-phase three-limb" core frameworks, to reduce material usage and minimize floor space. For example, the SCBH series dry-type transformers employ a dual-core framework design, achieving a more compact overall structure and weighing 30%–40% less than traditional silicon steel transformers.
2. Lightweight Enclosure
The enclosure is predominantly constructed from stainless steel or galvanized steel plates, with anti-corrosion treatments (e.g., phosphating for rust prevention) applied to the surface. It meets a protection rating of IP54 or higher, with certain models (e.g., KBSGZY series) supporting IP68 submersible operation. The enclosure design balances strength and lightweight properties, facilitating underground rail transportation (e.g., the KS9 transformer measures 950 × 600 × 850 mm and weighs 365 kg).
3. Modular Components
The interior consists of modular components, including an amorphous alloy core, high- and low-voltage windings, upper and lower clamping structures, and channel steel supports. The core and windings utilize an independent fixation system with elastic gaskets to minimize stress transfer, preventing increased no-load losses due to core compression.
II. Key Component Appearance Details
1. Amorphous Alloy Core
The core is wound from amorphous alloy strips, exhibiting a silvery-gray metallic luster without the grain boundaries characteristic of traditional silicon steel sheets. The core framework is reinforced with angle steel at all four corners, while upper and lower clamping structures form a framework to ensure mechanical stability.
2. Winding Design
The windings employ circular cross-section conductors, arranged in three layers around the core columns and coated with insulating material. Low-voltage windings predominantly use copper foil with inner-layer support from glass fiber-reinforced plastic, enhancing short-circuit withstand capability. For instance, the SBH15 series transformers optimize winding structure to reduce short-circuit impedance to 4%–6%.
3. Terminals and Outlet Boxes
High- and low-voltage outlet boxes adopt cable terminal box designs, sealed with potted insulating compound to prevent moisture ingress. The outlet boxes are equipped with electrical interlock mechanisms that automatically cut off power when opened, accompanied by "No Live Opening" warning labels. The high-voltage side terminal box additionally features an emergency stop button for rapid disconnection of the high-voltage input power.
III. Appearance Craftsmanship and Labeling
1. Surface Treatment Processes
The enclosure surface is coated with anti-rust paint, while flameproof surfaces undergo phosphating treatments. Bolts have a strength grade of no less than 8.8. Elastic gaskets are inserted between the core and windings to reduce vibration and noise. For example, the SCBH17 series employs specialized damping materials to lower operational noise to below 50 dB.
2. Labeling and Certification
The enclosure prominently displays the Mine Product Safety Mark (MA mark), explosion-proof certification number, and applicable standards (e.g., GB 3836.1-2021). Capacity labeling is clear, such as "SCBH-1000/10," indicating a rated capacity of 1000 kVA and a high-voltage side voltage of 10 kV for an amorphous alloy dry-type transformer.
3. Protection and Monitoring Interfaces
Reserved interfaces for temperature sensors enable real-time winding temperature monitoring. Certain models (e.g., SH15-M series) integrate oil level indicators supporting oil injection, vacuum evacuation, and oil replenishment functions to prevent moisture ingress.
The main products include oil immersed transformers, dry-type transformers, power transformers, amorphous alloy transformers, mining transformers, box type substations, high and low voltage switchgear and supporting products
